Simulation and analysis of the dynamic characteristics of the internally carried air-launched aircraft

To ensure the security of the entire air-launched carrier rockets system is an important issue in the research work. As the most expensive part of the system, the numerical simulation of the dynamic characteristics of the aircraft plays an important role. Dynamic equations of aircraft and its cargo during flight are derived in detail and dynamic models are established in accordance to the basic principles of theoretical mechanics and flight dynamics. The dynamic models are then utilized for the simulation of the process of the system. By comparing the simulation results and the real flight test measurements, the models are verified to be correct and precise. The dynamic characteristic of the aircraft under various conditions is also analyzed.
